512M bits DDR2 SDRAM
EDE5104AESK (128M words × 4 bits)
EDE5108AESK (64M words × 8 bits)
Description
The EDE5104AESK is a 512M bits DDR2 SDRAM
organized as 33,554,432 words × 4 bits × 4 banks.
The EDE5108AESK is a 512M bits DDR2 SDRAM
organized as 16,777,216 words × 8 bits × 4 banks.
They are packaged in 60-ball FBGA (µBGA) package.
Features
• Power supply: VDD, VDDQ = 1.8V ± 0.1V
• Double-data-rate architecture: two data transfers per
clock cycle
• Bi-directional, differential data strobe (DQS and
/DQS) is transmitted/received with data, to be used in
capturing data at the receiver
• DQS is edge aligned with data for READs: center-
aligned with data for WRITEs
• Differential clock inputs (CK and /CK)
• DLL aligns DQ and DQS transitions with CK
transitions
• Commands entered on each positive CK edge: data
and data mask referenced to both edges of DQS
• Four internal banks for concurrent operation
• Data mask (DM) for write data
• Burst lengths: 4, 8
• /CAS Latency (CL): 3, 4, 5
• Auto precharge operation for each burst access
• Auto refresh and self refresh modes
• Average refresh period
7.8µs at 0°C ≤ TC ≤ +85°C
3.9µs at +85°C < TC ≤ +95°C
• SSTL_18 compatible I/O
• Posted CAS by programmable additive latency for
better command and data bus efficiency
• Off-Chip-Driver Impedance Adjustment and On-Die-
Termination for better signal quality
• Programmable RDQS, /RDQS output for making × 8
organization compatible to × 4 organization
• /DQS, (/RDQS) can be disabled for single-ended
Data Strobe operation.
• FBGA (µBGA) package with lead free solder
(Sn-Ag-Cu)
